From: Assessment and characterisation of common renal masses with CT and MRI
Multimodal presentation of a common type RCC on CT and MRI: CT (upper row): isodense in the native phase (arrow in a), hypervascular in the arterial phase with areas of necrosis (arrow in b) and early wash-out in the venous phase (arrow in c). MRI (middle and lower row): heterogeneous appearance on T2-weighted (arrow in d) and T1-weighted native (arrow in e) because of haemorrhage and necrosis, heterogeneous pattern on the ADC map (arrow in f), hyperenhancement in the arterial phase with areas of necrosis (arrow in g), early wash-out in the venous phase (arrow in h), and a tumour thrombus with contrast media enhancement reaching the renal vein and inferior vena cava (arrow in i)
